doilinks
~~~~~~~~~~~~~~~~~~~
Extension to add links to DOIs. With this extension you can use e.g.
:doi:`10.1016/S0022-2836(05)80360-2` in your documents. This will
create a link to a DOI resolver
(``https://doi.org/10.1016/S0022-2836(05)80360-2``).
The link caption will be the raw DOI.
You can also give an explicit caption, e.g.
:doi:`Basic local alignment search tool <10.1016/S0022-2836(05)80360-2>`.
